Indians For Guns

Mack The Knife,

What do you recommend me for cleaning the internals of the Milbro/Diana I am restoring. Can see lot of dirt and little bit of rust inside the cylinder and on the piston and spring.... The rifle has not been cared for for a number of years. How about soaking it in petrol and then wiping it dry...may be leave it out in the sun for sometime then to make sure all the petrol evaporates...? Or do you suggest something else....

Manish,

To remove the rust use what was used for the external surfaces.

To remove the gunk you could try petrol, diesel, acetone, surgical spirit or even immerse the part/s in boiling water and then give them a good scrub.

If you clean the parts with anything other than water, make sure that the parts are completely cleaned out with water before lubing and assembly.

Thanks Rustom...Will do....

about lubing an airgun what about an older gun which has a leather cup shaped washer ?

Hi All,
For PTFE in liquid form one can try NULON products. You can go their site nulonindia and order online. My bike is smooth after adding ptfe in the engine oil . Cost of 50 ml tin is Rs 90 including postage.
I am not sure it will work or not just my 2 cents

Hi!

I suggest do it the way it should be done- use a rust remover like one from Birchwood Casey. Remove deposits, especially from barrel using a solvent- RWS and other have excellent ones. After cleaning, use oils meant for each part of the gun- Air Chamber, external, barrel. Of course, this depend on the overall condition of the gun, how meticulous you want to be, and how much effort you want to make in finding parts if any are required. I had restored the Diana Mod-35 I had put up for sale in the Sale forum, and had followed the above procedure, including installing a John Knibbs spring, and replacing the Trigger assembly with an original got from France, and rebluing from Bisley.

In case that's the path you want to take, let me know if you need the solvent/oils etc- if you are near Mumbai/Chandigarh, I'll provide them free and help out with the restoration if required.

Regards,

Can anyone tell me how to lube the inside of the piston and the chamber with an even coat of lubricant...I plan to insert the piston first, the outside of which is lubed and only then introduce lube in the chamber...the idea is to avoid as much lubricant in front of the piston...the picture below (not good quality) could give you an idea...

KB article restored, please see the first post in this thread.
Cheers!

Hi Rustom,

Thanks very much for all the expert advice on lubing/ oiling etc. I have been wandering on the web and every expert advises differently.

I have been oiling my National 35; 0.22 as per one such adice. Remove the stock. Apply just a few drops of machine oil or Zorrix on the mainspring using a syringe. Also about one drop in the air exit near the breach. I still do not know how to dissemble the gun. Maybe you could post another educative post on this.

I also wish your expert adice on the following:

(1) Dieseling: How would I know I know when dieseling has happened? Although the gun shoots very well, I observe some black oily stuff on the spring. Is this due to dieseling or simple because of frictional rub off of a gun being broken in? Do I need to clean this? Can I agitate some rubbing spirit in the chamber (with dismantling), drain and dry this off?

(2) Some sites advice that new pellots should be oiled slightly. Will this be necessary after I clean and oil the bore after about every 1000 shots?

Thanks & BR,
Atanu

How about "Mobil" and "Castrol Moly Grease" inside My Diana 45 Compression Tube

Any make is fine as long as its moly grease. Use sparingly on all metal parts making contact with each other.

Is it available in India.
Thanks

It contains 2% moly looks like not good for Airgun.

They recommend 40~60% moly. Usually 60% are costly and very hard to get.
